Start by removing handles and arm rests etc whatever is obviously bolted on through the door panel then use a flat blade small putty knife to slide under the door panel along the bottom edge and pop the plastic clips that fasten the panel to the door.
Silverado door handle not working.
Inner door handle won t open on 2011 chevy silverado.
Due to bad engineering you have to replace the whole inside panel according to my gm service center i got it out of shop and two weeks later it broke again still have not fixed it because of the cost.
Since the door was bow open i pulled the door panel off and left all electronics attatched.
I found that the little ball on the end of the cable going to my inside door handle had came out of its slow.
Does it feel like the handles are jammed or just not engaging anything.
So i replaced it with one i had from previous trucks.
If the door will not open then the issue may be the latch but it may also be the linkage that connects the handles to the latch.
Work around the bottom and sides then the panel should lift off the window sill there may be some clips holding it there too.
The outside not working is really strange.
Inside door handle broke very easy i may say and then was told was 900 dollars to fix it.
Pretty easy job once you know how the door panel com.
It took a little work to force it back into place but once i got it back in place everything workedd perfectly fine again.
You will need to access the inside of the door panel to have access to the locking mechanism and door latch as well as verify the condition of that linkage.
